Here is  Crane Rail China Manufacturer  talking about Axle strength and heat load test.  If you have any idea about  Steel Crane Rail , welcome to contact us and discuss. Axle  strength and heat load test. At present, there is no physical axle strength test specification for  Chinese railways . All relevant units can only use different methods to test and test locomotive and vehicle axle components according to their respective needs, and according to their respective tests. Objective To determine the response load conditions and assessment criteria, and summarize the following tests. Static strength test under axle mechanical load: (1)  Test purpose and test content . The stress of the wheel web and the  axle parts  under the mechanical load is tested to check the static strength of the axle. (2)  Test methods and test conditions . Usually, the axles are composed of real wheel pairs, and the test is carried out by electric ...

Here is  Gb Standard Steel Rail Manufacturer  talking about What happened when the rails were repaired.  If you have any idea about  Gb Standard Steel Rail , welcome to contact us and discuss. The “Kata” issued by the torque wrench is generated by its own internal torque release structure. Its structure is divided into three structures: pressure spring, torque release joint and torque ram. The torque wrench is after the “Kata” sound is emitted. The prompt has reached the torque value you requested; first set the required torque value on the torque wrench (the spring is applied to the torque release joint by the spring sleeve), lock the torque wrench and start tightening the bolt. When the bolt reaches the torque value (when the torque is greater than the spring pressure), an instantaneous disjoint effect occurs. At the moment of the disjoint effect, a joint tap is struck, and the "Kata" sound from the metal casing of the wrench is sounded. This confirms the ...

Here is  Heavy Steel Rail Manufacturer  talking about Rail knowledge.  We know that the rails are mainly used on some steel rail roads or guide rails of some special vehicles. Its use is very important for us. Let's take a look at the rail knowledge explained by the rail manufacturers. Rails with a nominal weight of more than 30 kg per meter. Train rails and crane rails are heavy rails. Train rail : used to lay the railway, to withstand the pressure, impact load and friction of the train operation, requires sufficient strength and certain toughness. The quality requirements are strict. In addition to ensuring its chemical composition, it is also required to test mechanical properties, drop weight test and acid immersion low-fold structure. The production plants include WISCO, Anshan Iron and Steel, Baotou Steel and Panzhihua Iron and Steel. Steel Crane Rail : the crane rail, its height is low, the head width and waist thickness are large, only the chemical comp...

Here is  China Standard Steel Rail  talking about Rail on coal coke car.  If you have any idea about  High Quality Steel Rail , welcome to contact us and discuss. We know that coal coke cars are mainly underground or above-ground coal coke mining. It is a product of rail manufacturers to provide a certain track for the pavement to transport these coal coke products out of the surface. It can be seen that the rails are used in coal mining. It is very long-term use, then the rail manufacturers must pay attention to safety measures when using, in order to reduce the problem. Then, what protective measures are there in the construction? All construction workers must carry out three levels of safety construction education before entering the factory. The construction personnel must abide by the rules and regulations of the construction unit. Construction workers must wear labor protection supplies when entering the factory. Wear a hard hat and good overalls. Cons...

China Steel Crane Rail Manufacturer  said that because the rails require professional technology and professional equipment in production, they can make qualified product quality.  What technologies are used in the production and production of  High Quality Steel Rail  manufacturers? 1.  The use of off-furnace refining and vacuum degassing technology  to ensure the intrinsic quality of the billet, control the residual elements and gases in the steel to ensure the purity of the steel. 2.  The use of continuous casting blooms , mainly to improve the low-fold structure of the billet. The stepping furnace is used to heat the steel slab, which can effectively control the atmosphere in the furnace and prevent the steel from decarburization and heating temperature unevenness during heating. 3.  High-pressure water descaling technology . It is possible to greatly reduce the occurrence of defects such as rolling marks caused by the scale. 4....
